Fix compile warning generated by VC.

Add LooperWithTime.
Fix Bug: Change Lambda Capture from "&" (Keep Reference) to "=" (Copy).

Before this fix, the following code will cause a runtime error:

int AppMain()
{
	Window wnd("Title", 1280, 768);
	Renderer rnd = wnd.getRenderer();

	Looper lp;
	lp + make_pair(SDL_QUIT, []() {printf("Quit!\n");});
	lp.run();

	return 0;
}

Now, the bug is fixed~!
